Worlds First Computer Mouse

40 years ago a patent was applied for which described a wooden shell with two metal wheels. The device quickly received the nickname of a mouse due to it having a tail (wire) coming out of it. The patent described an X-Y position indicator for a display system.

Due to the patent expiring 20 years later in 1987, Engelbart did not receive much in the way of royalties as a computer mouse wasn’t too popular before that. Also this was partly due to the new mice using a different mechanism which did not infringe on the patent.
